I agree. Manchester is next, and other cities will follow.
What is important is that this isn't merely a tax-raising initiative. All the money raised goes to Transport for London. Not a single penny goes to the Treasury, and all the money is being invested in improving London's public transport. Literally billions of pounds is being spent on the Tube, and the congestion charge funding is making a very significant contribution to that and other public transport projects.
If the money was being siphoned off to do other things I could understand the criticism. It isn't being siphoned off. It is being invested in making a better public transport system for London. The congestion charge is contributing to further improvements in bus, train and tram services.
We have to get away from the idea that each of us has an unalienable right to drive when and where we wish, for doing things that way will only lead to oblivion.
I frequently visit London. If I am going anywhere within the North and South Circular Roads, I drive to a railway station and take the train. Parking is reasonable, costing £3.50.
The train service is excellent, and it is cheap outside the morning peak. A one day off peak Travelcard costs me £7.80, and gets me anywhere in Zones 1-6. That wouldn't even pay for the fuel in my car, and going by train, my contribution to atmospheric carbon dioxide is a tiny fraction of the car's.
Don't get me wrong. I love driving, and I love my Mercedes-Benz. But I am not under any illusion about asserting "rights" that I simply do not have. We all have obligations and responsibilities too.
